Why codes might not work
- The code has expired and is no longer supported by the current version of Build A Gun.
- The code was typed with a typo, missing character, or extra space; codes are case-sensitive and must match exactly.
- The code was already redeemed on your Roblox account, so it cannot be claimed again.
- The server you joined is running an older build; rejoin Build A Gun or restart Roblox and try again on a fresh server.
